NOTE: At no time should the Concentrate
Valve ever be completely closed. RO system
must have some water running to the drain
during production or RO water.
NOTE: DO NOT operate over 150
psi, as this will damage membrane.
The back pressure will read less
than 150 psi.
Start Up
ü
Ensure power switch (located on top of control Box).
(#1) is in the OFF position.
ü
Plug the unit into an appropriate power supply.
ü
If installing a pressure Tank system, open the Ball
Valve (#2) on the Bulkhead.
ü
Turn the Blending Valve to coldest setting [90°]. (#3)
ü
Fully open the Concentrate Needle (#4) Valve by
turning it counter clockwise.
ü
Fully close Recirculate Needle Valve (#5) by turning it
clockwise.
ü
Turn the incoming water supply on the RO processor
to the “ON” position.
ü
Turn the Power Switch (#1) to “ON” position.
•
The Water inlet solenoid valve will open.
•
There will be a 5 second delay before the pump
starts.
•
The system may cycle on and off automatically
during initial start up as air is purged from
system.
•
Allow the unit to run for 5 minutes while excess
air is being purged from system.
ü
Close the Concentrate Needle Valve (#4) until the
Feed Pressure Gauge(#6) reaches a max. of 150 psig.
ü
Open the Recirculation Needle Valve (#5) until the
unit Feed Pressure Gauge (#6) drops to 140 psig.
ü
Close the Concentrate Needle Valve (#4) until 150 psig is again achieved on the Pump Feed
Pressure Gauge (#6).
Repeat
underlined
sequence until both flow meters read equal flows and feed pressure gauge reads
150 psi. At this point the RO processor is operating at its maximum efficiency potential.
If using a Pressure Tank, system will continue to operate until Tank Pressure Gauge reads 60 psig or
Float Tank, upper float switch is triggered by the water level.
